Order for essential singularites

WebThe value of m for which this occurs is the order of the pole and the value of a-1 thus computed is the residue. 2. Residues at essential points. Residues at essential singularities can sometimes be found by using known series expansions. Example. In the function f(z) = e-1/z, z = 0 is an essential singularity. Webfunctions with poles of fairly low order. However, it becomes increas-ingly difficult the higher the order of the pole, and impossible with essential singularities. In these cases, we have no choice but to return to the Laurent expansion. Example 1.4. Find the residues of f(z) = sin(z)/z2 and g(z) = e−1/z2 at z = 0 and use it to evaluate Z C ...
